4 Lessons Learned: Coatings
Mueller Corp: How to Metallize Plastics
For mechanical and aesthetic purposes, plastic parts can be coated with metal which is called metallization. Plastic parts which are coated with metal feature reflectivity and gloss. Through the process of metallization, plastic components achieve the properties of electrical conductivity and abrasion resistance. Although not in all situations, plastic components which are metallized are used in similar applications where metal parts are usually used with lower weight. There are different methods of metallizing plastics including vacuum metallization, plating, or arc or flame spraying. There is also a possibility of metallizing transfer films and use them as alternative techniques in applying film onto a substrate surface. Whatever industry you are in right now, Mueller Corp is your number one source of plastic metalized components.
When it comes to the process of vacuum metallization, washing and coating of the plastic component is done first so that the metal layer is smooth and uniform. The next step involves the evaporation of metal, like aluminum, in a vacuum chamber using a vacuum chamber and the vapor is condensed into the substrate’s surface, leaving a thin layer of metal coating. To prevent oxidation, the entire process happens within the vacuum chamber. A top coat can be applied depending on the plastic component’s application in order to increase properties like abrasion resistance. Plastic components that are metabolized are usually used in different applications most especially automotive interior parts and home appliances.
In arc and flame spraying, a hand-held device is used in spraying a layer of metallic coating on the substrate. In flame spraying, metallic powder is heated and then melted using combustion flame in accelerating the mixture and the spray is released. Coatings can be applied into specific areas because of the easy application, allowing working with unnaturally shaped parts and complex components. The process of electroless plating and electroplating are more effective than vacuum metallization which produces strong adhesion coats, and electroplating used uses electric current while an electric current is not used in electroless plating. Electroless plating is used in depositing copper or nickel metal into plastic substrates.
